The Transmission Company of Nigeria (TCN) has announced a fresh power outage in parts of Abuja following the tripping of a 100MVA transformer at its Apo 132kV/33kV Transmission Substation.
TCN disclosed this in a notice issued on Wednesday, saying the transformer, identified as TR4, tripped in the early hours of the day.
According to the company, oil spillage was observed on the red-phase high-voltage bushing of the transformer, resulting in the loss of four 33kV feeders—H31, H33, H35 and H37.
TCN said its maintenance team had commenced investigations to determine the exact cause of the fault and facilitate repairs and restoration of the affected transformer.
“The 100MVA TR4 transformer at the 132/33kV Apo Transmission Substation tripped in the early hours of today.
“Our maintenance crew are already carrying out a detailed investigation on the transformer to ascertain the exact cause of the tripping, to enable us effect repairs and restore the transformer,” the company said.
The development has resulted in power outages in parts of the Federal Capital Territory, including Apo Legislative Quarters, Lokogoma, Apo Resettlement and surrounding areas.
The Abuja Electricity Distribution Company (AEDC) also confirmed the disruption, advising affected customers to await further information on restoration.
The latest outage comes shortly after TCN announced a blackout in parts of Abuja as a result of scheduled maintenance work.
TCN said efforts were ongoing to identify and rectify the fault and restore electricity supply to the affected areas.
